Rules:
- Normal sudoku rules apply.
- The green line is a German Whisper; its digits must have a difference of at least 5.
- The red line is a parity line; it must contain one even digit and one odd digit.
- The purple line is a renban; it must contain three consecutive digits (but they can be arranged in any order).
- The yellow line is entropic; it must contain one low digit (1, 2 or 3), one medium digit (4, 5 or 6) and one high digit (7, 8 or 9), in any order.
- Adjacent digits on ANY line must sum to 10 or 11.

Another fun idea. I didn't realise how restrictive the 10/11 idea was at the outset. Thank you for another lovely puzzle!

Forgot that EVERY line needed to add to 10/11, not just the grey lines :(

Nice puzzle! I agree with LapsedMemory that there is a moment where you feel overwhelmed, and then it all clicks. Thanks for setting!

Very nice puzzle with a very cool break-in. Intimidating at first glance, but the rules paint some very neat little logic bombs all over the grid.
